Some clocks provided on Ingenic SoCs have dividers, whose hardware value
as written in the register cannot be expressed as an affine function
to the actual divider value.
For instance, for the CPU clock on the JZ4770, the dividers are coded as
follows:
------------------
| Bits | Div |
------------------
| 0 0 0 | 1 |
| 0 0 1 | 2 |
| 0 1 0 | 3 |
| 0 1 1 | 4 |
| 1 0 0 | 6 |
| 1 0 1 | 8 |
| 1 1 0 | 12 |
------------------
To support this setup, we introduce a new field in the
ingenic_cgu_div_info structure that allows to specify the divider table.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
